This is a simple single-piece, printed juicepress that snugly fits on top of a standard 250ml can. 

The juice from the fruit pours into the can thrugh a hole that aligns with the hole on top of the can, meaning the can needs no modification apart from beeing opend. The press fits snugly on top of the can and it can hold on to a full can while still beeing eazy to install and remove.

I was surpriced how little spillage there was while testing the design, there was no spillage at all in fact, not even on top of the can. Cleaning afterwards is eazy since the design is simple with no small crevices or such.

It takes about 2.5 small oranges to fill it up from my testing. I've only tried it with oranges but the squishy thing is small enaugh to press both lemons and limes. This means that you can use this juicepress on top of a can mostly filled with the original content to add some freshly squished lemonjuice to it. 

This is the third revision of the design and now i'm happy enaugh to release it to the public. I will take in feedback and make alterations accordingly in the future.
